Industrial life assurance had its beginnings during the Industrial Revolution, hence the name, when some companies provide life assurance for the working population, using a system of regular collections of premiums at frequent intervals (usually weekly) at the homes of the policyholders. This avoided the burden of saving for a year to pay for other types of policies. Originally this type of insurance stemmed from the need to provide a sum assured to cover burial expenses. Most of the industrial companies also transact ordinary life assurance in the policyholder's home and are known as the 'home service offices'.
